text: In 1987 Canada witnessed a crisis in the seafood industry. Shellfish toxins present in PEI mussels caused amnesic shellfish poisoning taking several lives. In response, shellfish toxin research was initiated at NRC Canada. Today, NRC remains the premier producer of biotoxin CRMs in the world and is recognized for its expertise.
